OILPAN FOR SEWNG- MACHNES.

Application :filed May 23, 1925.

AMy invention relates to new and usefulV improvements in an oil pan for sewing machines, and more particularly relates to a receptacle designed for placement within a tray used in connection with power sewing machines such as are installed in factories making wearing apparel, and has for its primary object to provide a pan which will catch any oil dripping from the machine. and prevent it coming in contact with any part of the tray or table so that the goods being worked upon will not be damaged.

In the use of sewing machines of the high speed type it is necessary to keep the mechanism well lubricated which is often over done and to such an extent that a considerable amount drips from the machine and even where drip pans have been used the oil is allowed to accumulate until it reaches the bed or base of the machine from which it will run olf onto the tray or table and form a hlm on the surfaces thereof and the constant accumulation of such a film causes the woodwork of the tray and table to become thoroughly saturated so that when the goods from which wearing apparel is made is brought into contact with the surfaces of the table or tray said garment must be dis-v posed of as a second or discarded with the consequent loss in time or material or both.

One of the objects of my invention is to overcome these disadvantages by producing an oil pan in which the machine is set so that any accumulation of oil on the machine it self cannot come in contact with the table or trap and therefore these will always be kept in a perfect condition so far as oil saturation is concerned. I

A further object of the invention is to produce an oil pan for the reception of a sewing machine, said pan having an inclined drain groove in its bottom adjacent the front of the pan and leading to a pipe by which the oil may be conveyed to a point of disposal, as into a small receptacle attached to the pipe or to any size receptacle adjacent the machine or any part of the building in which the machine mightbe located and to further provide the pan with a rear wall of greater height than the others to form a splash plate to prevent any oil splashings from reaching the rear wall of the tray.

With these ends in view, this invention consists in the details of construction and combination of elements hereinafter set Serial No. 32,294.

forth and then specifically designated by the claims.

ln order that those skilled in fthe art to which this invention appertains, may understand how to malte and use the same, l will describe its construction in detail, referring by numerals to the accompanying drawings forming a part of this application, in which Fig. 1 is a fragmentary sectional view of a table and trayv looking at the rear of a machine placed in a pan embodying my invention, portions of which are broken away and shown in section to bring out detailsvof construction.

Fig. 2 is a. plan view of the improved o il pan illustrating the manner in which a sewing' machine sets therein.

F ig. 3 is a fragmentary transverse sectional view of the table, tray and pan.

Fig. 4 is a perspective view of the oil pan embodied in my invention.

Fig. 5 is a section at the line 5 5 of Fig. fl.

In carrying out my invention as herein embodied, 2 represents the usual wooden table employed in factories for supporting sewing machines and on this is mounted a tray 3 including particularly a. bottom 4l, sides 5, ends 6 and a top 7 and lusually one of these trays is employed to enclose the base or bed plate of a sewing machine convcntionally shown at 8 and including a control lever 9 to which is connected one yend of a chain 10, or its equivalent passing through the table and tray to a point beneath the former for operation by the knee or foot of the operator in controlling the feed or operations of the machine.

My improved oil pan is designated by the v numeral 11 and may be made of met-al or other suitable material so fashioned as to provide a bottom 12, ends 14 and sides 1,5, the rear side being of greater height than .the front side so as to form a portion pro- `jecting above the top edge of the pan and constituting a splash plate 1G. Adjacent one end of the pan at the rear thereof is formed an opening 17 for the passage of the chain 10 and this opening is surrounded by a stand pipe 18 rising to a point approximately in line with the upper edge of the end walls so that if by any chance whatever accumulations of oil within the pan should rise to the top thereof the oil will not run into the stand pipe and onto the control chain and sai-d stand pipe also acts as a shield for the chain regardless of the level of the oil within the pan.

In the bottom wall 12 of the pan adjacent the front side thereof is formed a longitudinal channel or depression 19 inclined toward the end of the pan opposite the position of the stand pipe 18 and leads to an outlet pipe 20 by which the accumulations of oil in the pan ina-y be conveyed to a place of disposal such as a receptacle placed directly under the machine table or any desirable location within the building or even to a sewerage disposal system. This drain channel being pressed from the bottom wall of the pan forms a protuberance on the under face and therefore a groove 21 is formed in the upper face of the bottom wall l of the tray to accommodate the walls of the channel while aligned holes are formed in the tray and table for the reception of the outlet pipe 20 and likewise other aligned holes are formed in the tray and table with which the hole 17 in the pan bottom will align for the passage of the chain 10, as plainly shown in Fig. 1. Y

The oil pan is fastened in the tray by the saine fastening means which hold the machine in position, such fastening means being here shown as the usual machine screw 22 passing through the table and tray and having threaded connection with the base or bed plate of the machine and a wood screw 23 passing through the base or bed plate of the machine and being threaded into the tray and table. In order to pass these screws through the pan I provide a hole 2.1i for the machine screw and another hole 25 for the wood screw and to prevent leakage of oil about the screws washers 26 are placed about them between the machine base and pan or between the pan and bottom wall of the tray.

From the foregoing description it will be noted particularly that any oil ydripping into the pan will be carried ott by the outlet pipe 20 to a place of disposal and since the machine is actually mounted within the pan any oil which may accumulate or run along any part of the machine itself cannot come in contact with the woodwork yof the table or tray and therefore cannot stain the goods being sewn.

Of course l do not wish to bel limited to the eXactdetails of construction as herein shown as these may be varied within the limits of the appended claims without departing from the spirit of my invention.

Having thusfully described my invention, what I claim as new and useful is 1. In an oil pan for sewing machines, the combination with a supporting member and a machine, of a pan resting on the supporting member and in which the machine is set, an outlet pipe connected with sai-d pan and passing through the supporting member, a stand pipe within the pan through which a portion of the machine passes, and means to fasten the machine to the tray and thereby clamp the panin position.

2. The structure set forth in claim 1 wherein the bottom of the pan is provided with an inclined channel beneath the base `of the machine and at one side of the center thereof reaching to the outlet pipe.

8. The herein described combination of a table, a tray on said table, a pan occupying a portion of the tray, and a sewing machine within the pan, said pan having a longitudinal drain channel at one side of the center of its bottom wall leading to an outlet pipe disposed bevond the base of the machine and passing through the tray and table and provided with a stand pipe at the opposite end of the pan registering with a hole inthe bottom of the pan and opening in the tray for the passage of a machine operating ele'- ment and said pan and tray further having holes in its bottom for the passage of securing devices to simultaneously fasten all parts together.

4I. An ,oil pan for ing a bottom wall for the passage of different devices and r0- vided adjacent one side with a longitudinal inclined drain channel, end walls, a front side wall, and a back side wall, the latter having an extension projecting above the edges of the other walls and constituting a splash plate, an Ioutletpipeleading from sewing machines includthe channel and a. stand pipe surrounding one of the holes in the pan bottom and projecting to a height substantially the same as the end walls.

In testimony whereof, I Vhave hereunto aiiixed my signature.
